   Abstract = {© 2019 INFORMS We study the contagious switching behavior
             related to a consumer’s choice of wireless carriers, that
             is, that a consumer is more likely to switch wireless
             carriers if more of their contacts from the same carrier
             have switched. Contagious switching (or a positive network
             effect) can be driven by information-based social learning,
             as well as other mechanisms related to network size.
             Although previous marketing literature has documented the
             social-learning effect, most of the applications studied
             involve products in which consumers usually do not enjoy any
             direct benefits from a large network other than from
             information-based social learning. We explore the importance
             of the social-learning effect relative to other mechanisms
             that may also lead to the network effect. We propose a
             dynamic structural model with interpersonal interactions. To
             model the social-learning effect, a consumer uses feedback
             from his or her contacts who have switched from a focal
             carrier to update his or her quality expectations of
             alternative carriers. Our model further accounts for two
             unique aspects of consumer strategic learning: (i) the
             individual’s perception on the signal of alternative
             carriers from contacts who switch is systematically
             different according to whether the signal comes from a loyal
             contact; and (ii) that the perceived noisiness of the signal
             on alternative carriers from a contact who has switched
             depends on the strength of the relationship between the
             individual and the contact. The remaining network effect not
             captured through social learning is modeled as a function of
             the size of the network. We solve the model with a two-step
             dynamic programming algorithm, with the assumption that a
             consumer is forward-looking and decides whether to stay with
             the same service carrier in each period by maximizing the
             total utility received from that day onward. We apply the
             proposed model to the data set of a mobile network operator
             in a European country. We find that churning/switching
             behavior is contagious in the network context and that
             one-third of general network effects can be attributed to
             social learning. We also detect strategic learning by
             consumers from their contacts in two ways: the experience
             signal on alternative carriers from a more loyal contact who
             has switched from the focal carrier is perceived to be more
             positive than that from a less loyal contact; and the
             social-learning effect is stronger from an individual’s
             closest contacts. The simulation analysis demonstrates the
             value of our model in helping a company prioritize its
             customer relationship management effort.},

   Abstract = {© 2018 Elsevier Inc. Taking the early U.S. automobile
             industry as an example, we evaluate four competing
             hypotheses on regional industry agglomeration:
             intra-industry local externalities, inter-industry local
             externalities, employee spinouts, and location fixed
             effects. Our findings suggest that in the automobile case,
             inter-industry local externalities (particularly from the
             carriage and wagon industry) and employee spinouts
             (particularly due to the high spinout rate in Detroit) play
             important roles. The presence of other firms in the same
             industry has a negligible or negative effect. Finally, local
             inputs account for some agglomeration in the short run, but
             the effects are much more profound in the long
             run.},

   Abstract = {© The Author(s) 2017. Published by Oxford University Press
             on behalf of The Review of Economic Studies Limited. In this
             article, we use micro data on both trade and production for
             a sample of large Chinese manufacturing firms in the
             footwear industry from 2002 to 2006 to estimate an empirical
             model of export demand, pricing, and market participation by
             destination market. We use the model to construct indexes of
             firm-level demand, marginal cost, and fixed cost. The
             empirical results indicate substantial firm heterogeneity in
             all three dimension with demand being the most dispersed.
             The firm-specific demand and marginal cost components
             account for over 30% of market share variation, 40% of sales
             variation, and over 50% of price variation among exporters.
             The fixed cost index is the primary factor explaining
             differences in the pattern of destination markets across
             firms. The estimates are used to analyse the supply
             reallocation following the removal of the quota on Chinese
             footwear exports to the EU. This led to a rapid
             restructuring of export supply sources on both the intensive
             and extensive margins in favour of firms with high demand
             and low fixed costs indexes, with marginal cost differences
             not being important.},

             the model with data from Colombian manufacturing frms before
             the 1991 trade liberalization. A counterfactual trade
             liberalization is broadly consistent with postliberalization
             data. It increases skill intensity from 12 to 16 percent,
             while decreasing sales. Imported inputs, estimated to be of
             higher quality, and domestic input linkages are
             quantitatively important. Economies of scale, export
             expansion, and reallocation of production are small and

             in a quantitative model with endogenously variable markups.
             We find that trade can significantly reduce markup

             extensive misallocation, and (ii ) opening to trade exposes
             hitherto dominant producers to greater competitive pressure.
             We measure the extent to which these two conditions are
             satisfied in Taiwanese producer-level data. Versions of our
             model consistent with the Taiwanese data predict that
             opening up to trade strongly increases competition and
             reduces markup distortions by up to one-half, thus
             significantly reducing productivity losses due to

   Abstract = {We use producer-level data to evaluate the role of financial
             frictions in determining total factor productivity (TFP). We
             study a model of establishment dynamics in which financial
             frictions reduce TFP through two channels. First, finance
             frictions distort entry and technology adoption decisions.
             Second, finance frictions generate dispersion in the returns
             to capital across existing producers and thus productivity
             losses from misallocation. Parameterizations of our model

             In the dentist industry entry costs were subsidized in

   Abstract = {Successful exporting countries are often seen as successful
             economies. This paper studies the role of new exporting
             entrepreneurs-defined as firms that became exporters-in
             determining export growth in a fast growing and export
             oriented middleincome country i.e., Costa Rica during
             1997-2007. It provides a detailed description of the
             contribution of export entrepreneurs in the short and long
             run, and comparing the observed patterns with an emerging
             literature on the role of the "extensive" margin in
             international trade. On a year-by-year basis, the rate of
             firm turnover into and out of exporting is high, but exit
             rates decline rapidly with age (i.e., the number of years
             the firm has been exporting). On average, about 30 percent
             of firms in each year tend to exit export activities, and a
             similar percentage of firms enter. The exiting and entering
             firms tend to be significantly smaller than incumbent firms
             in terms of export value (e.g., entrants export about 30
             percent less on average than incumbent firms). These
             findings are consistent with existing evidence for other
             middle income Latin American countries. However, in the long
             run new product-firm combinations (i.e., product-firm
             combinations not present in 1997) account for almost 60
             percent of the value of exports in 2007. Surviving new
             exporters actively adopted new products (for the firm, but
             not necessarily new for the country) and abandoned weaker
             existing products they start with, and their export growth
             rates were very high during a period (1999-2005) when those
             of incumbent exporting firms were actually negative. © The

   Abstract = {Government policies that impose restrictions on the size of
             large establishments or firms, or promote small ones, are
             widespread across countries. In this paper, we develop a
             framework to systematically study policies of this class. We
             study a simple growth model with an endogenous size
             distribution of production units. We parameterize this model
             to account for the size distribution of establishments and
             for the large share of employment in large establishments.
             Then, we ask: quantitatively, how costly are policies that
             distort the size of production units? What is the impact of
             these policies on productivity measures, the equilibrium
             number of establishments and their size distribution? We
             find that these effects are potentially large: policies that
             reduce the average size of establishments by 20% lead to
             reductions in output and output per establishment up to 8.1%
             and 25.6% respectively, as well as large increases in the

   Abstract = {We develop a simple framework to address government policies
             that restrict the size of establishments in a particular
             sector. The economy we study is a two-sector extension of
             the span-of-control model of Lucas [Lucas, R.E., 1978. On
             the size distribution of business firms. Bell Journal 9,
             508-523]. In the model, production requires a managerial
             input, and individuals sort themselves into managers and
             workers. Since managers are heterogeneous in terms of their
             ability, establishments of different sizes coexist in
             equilibrium in each sector. We then study government
             policies that aim to change the size distribution of
             establishments in a given sector, such as Japan's Large
             Scale Retail Location Law. How costly are these policies?
             What is their impact on productivity, the number and size
             distribution of establishments? We find that these effects
             are potentially large. © 2005 Elsevier B.V. All rights
